Hi Folks, Pls. excuse me for sending this again. Unfortunately, I haven't got any satisfactory answer yet. How the other portable implementation of RSVP(TE) from vendors like Data Connection, Trillium, Netplane and Future Soft take care of this. How their portable implementation of RSVP intercept and receive the RSVP protocol messages on SunOS/Solaris when running on transit nodes? They claim to be providing portability for SunOS/Solaris though. Which socket option to be used???? Or something special needs to be done???? Any response shall be greatly appreciated. Thanks in advance.
